The Key To The Best Homemade Root Beer Float Is All In The Glass

For many people, a root beer float is a timeless treat that brings back instant nostalgia. Creamy vanilla ice cream swirled with bubbly root beer is  nothing less than a match made in heaven. But while many focus on the quality of the ingredients (which certainly does matter), one often-overlooked detail can take your float to the next level. That would be the glass in which it's served.

The type of glass you use for your float isn't just about aesthetics — it also affects the experience, sometimes dramatically so. A tall, chilled glass is best for making a root beer float that's visually appealing and maintains the right temperature. Such a frosty vessels also helps keep the root beer cold for longer, ensuring the carbonation doesn't flatten too quickly. This also allows the ice cream to soften just enough to create that creamy, fizzy magic without melting right away. And, sure, the look is nice, too, as the frosty layer on the outside of the glass can also help your float feel more luxuriant. To achieve all that frosty perfection, simply place your glass in the freezer for at least 10 to 15 minutes before making your float.  

First, consider the kind of root beer that you would want to drink on its own. Go for craft root beers with natural flavors and just the right amount of sweetness. Avoid overly sugary brands that can overwhelm the ice cream. And why not get creative when it comes to ice cream flavors, too? Olive oil ice cream may just hit the spot. Or see how your float comes out if you use a less-rich but potentially more flavorful gelato instead of ice cream. Take your float up a notch with whipped cream or caramel sauce.

And how exactly should you assemble your float? While there's no definitive rule, starting with the ice cream ensures the root beer cascades over it, creating that foamy top. Plop two scoops of ice cream into your glass, then slowly pour chilled root beer to avoid overflow. Here's how to get the perfect pour if your root beer comes in a can.

Of course, you want your float to be cold, but you don't want to wind up with frozen fingers. These tall glass beer stein-style mugs with handles are perfect. A chilled glass might seem like a small detail, but it's key to enjoying your best root beer. The next time you crave this classic treat, don't skip the freezer step — it's worth it.
